- Saturn is approximately 10 times as far away from the sun as the earth. This means that its orbital acceleration is ________ that of the earth.A. 1/10B. 1/100C. 1/1000D. 1/10,000The planet Saturn orbits the Sun at an average distance of 888 million miles. Use Kepler’s 3rd law to find the period of Saturn’s orbit, in Earth years.Europa orbits Jupiter with an average radius of 671,100 km and a period of 3.551 days. Based upon these data, what is the mass of Jupiter (in kg)? |kg
- The radius of the Earth's orbit is 1.50 x 1011 m and that of Neptune is 4.52 x 1012 m. The star that this planet orbits is identical to our Sun. What is the orbital period of this planet? 2.2 years eBookYou land on Mars and observe that one of its moons (Phobos) has an orbital period of 7.66 hours. If the Phobos were farther from Mars than it is now, it’s period would be a) less than 7.66 hrs. b) about 7.66 hrs. c) more than 7.66 hrs. d) difficult to predict without more information.Please answer this question
- Kepler's 1st law says that our Solar System's planets orbit in ellipses around the Sun where the closest distance to the Sun is called perihelion. Suppose I tell you that there is a planet with a perihelion distance of 2 AU and a semi-major axis of 1.5 AU. Does this make physical sense? Explain why or why not.According to Lunar Laser Ranging experiments the average distance LM from the Earth to the Moon is approximately 3.85 × 10° km. The Moon orbits the Earth and completes one revolution in approximately 27.5 days (a sidereal month). How can the mass of the Earth be calculated using the information above? Select the correct statements. Select one or more: O a. Use Newton's third law. O b. Use Newton's first law. c. Use Coulombs law. O d. Use Newton's second law.6. True or false, if Earth were twice as massive but it revolved at the same distance from the sun, it's orbital period would be 2.88 years
- Which of the following are, or follow directly from, Kepler's Laws of planetary motion? Check all that apply. More distant planets move at slower speeds. The force of attraction between any two objects decreases with the square of the distance between their centers. The orbit of each planet about the Sun is an ellipse with the Sun at one focus. A planet travels faster when it is nearer to the Sun and slower when it is farther from the Sun. As a planet moves around its orbit, it sweeps out equal areas in equal times.A satellite encircles Mars at a distance above its surface equal to 3 times the radius of Mars. If gm the acceleration due to gravity at the surface of Mars, what is the acceleration due to gravity at the location of the satellite? A. gm/16 B. gm/9 C. gm/4 D. gm/3 O B O ACalculate the period of a satellite orbiting the Moon, 91 km above the Moon's surface. Ignore effects of the Earth. The radius of the Moon is 1740 km.
